i'm bianna golodryga. >> and i'm dan harris. this is saturday, september 11th. >> this morning, anger and remembrance. nine years after 9/11, it's the most heated anniversary yet. with protests planned amidst the memorials. and now, that controversial pastor has arrived in new york. we're live at ground zero and with the latest. what went wrong? at least four people dead in california after that massive gas line explosion leveled an entire neighborhood. how could this have happened? and how safe are the pipelines that run beneath our streets? reversing course. iran now says it's delaying the release of one of the american hikers imprisoned there. she was supposed to be set free this morning. but her health is still at risk. we have the latest. and standing up to cancer. actors and activists, musicians and media titans, team up to fight cancer. and we have the highlights this morning.

>> that was our very own robin roberts. diane sawyer participated in the program to fight cancer. and to remember those lost to the disease, as well. good morning, everyone. today is also a day of remembrance for 9/11. it's cloaked in so much controversy this year. across the country, there will be memorials. at ground zero, family members are gathering to pay tribute to the loved ones they lost nine years ago. and vice president biden arrived moments ago to pay his respects. president obama will pay respects to all those who died that day, at the pentagon. and the first lady will be in pennsylvania, where brave passengers brought down flight 93, believed to be on-target to crash into the u.s. capitol or the white house. >> as you noted, this year's remembrances take place against a highly-political backdrop. pastor terry jones arrived in

new york city late last night. he is hoping to meet with the imam behind the cultural at ground zero. there's protests raising questions whether the damage has been done anyway. we begin at ground zero. for months, it has been a site of protest over the proposed mosque. today is no exception. but there will also be memorials. john berman is there live. good morning, john. >> reporter: good morning, bianna. it's a beautiful morning here in new york, just as it was nine years ago, as many people remember. there will be the solemn ceremonies. but also today, also controversy. the dueling demonstrations. for the proposed islamic center and for the arrival of that pastor from florida. >> you had a lot to say before. >> reporter: not a lot of words

from pastor terry jones, as he arrived in new york city late last night, after a week of a circus atmosphere in gainesville, florida, where jones staged his on again/now off again threat to burn the koran. >> there will be no koran burning tomorrow. do we have to repeat that over and over again? >> reporter: however, jones is still calling for a meeting to discuss the construction of the islamic center near ground zero. >> we have not heard from the imam. but we are very hopeful that we will meet with him. >> reporter: imam feisal abdul rauf says there's no meeting planned. but he's open to seeing anyone committed to seeking peace. the islamic center is the focus of dueling demonstrations today. >> my son is dead. he was murdered by muslims. he can't speak anymore. and i'll speak out for him. i think that's the american way. we'll let our voices be heard. >> reporter: and once again, the president weighed in. using his most forceful language yet, to defend the right to build the center. >> we have millions of

muslim-americans, our fellow citizens in this country. when we start acting as if their religion is somehow offensive, what are we saying to them? >> reporter: and he added there are muslims serving in u.s. uniform overseas. >> part of our service is making sure they understand that we don't differentiate between them and us. it's just us. >> reporter: the new york police department says they are expecting thousands of demonstrators down here today. however, they are putting extra officers on the street, mostly to keep the demonstrators separated. and they will also keep their eye on the reverend terry jones here in new york city, trying to keep him safe. he will be here until monday. >> john berman, thank you. over in afghanistan this morning, people are celebrating eid, the holiday that ends the holy month of ramadan. along with celebrations, thousands of people are also

protesting that plan to burn korans in florida, even though it's been called off. our martha raddatz is in kabul this morning. she has the latest from there. martha, good morning. >> reporter: good morning, dan. clearly, some damage has already been done. protests are erupting here and across the muslim world. thousands of protesters gathered across afghanistan, even after it was clear that the koran would not be burned. clashes with police left nearly a dozen people injured. the commander of troops in afghanistan, general david petraeus, told us he fears jones has created indelible images of hatred. >> there's already, in a sense, images, if you will, implanted in minds. >> reporter: general petraeus was one of the first to condemn terry jones this week, fearing for the safety of the 100,000 u.s. troops and others under his command. an especially powerful feeling on this anniversary. >> they and their families have sacrificed enormously during this time. our country can never thank them

enough. >> reporter: petraeus visited many of his troops this week. he also expressed frustration that nine years after the 9/11 attacks osama bin laden has not been found. >> to say he's gone underground, he's not as influential or whatever, that would be misplaced. he's an iconic figure. he still is the leader of al qaeda. he still periodically issues instructions. provides inspiration to those extremists who are out there. >> reporter: and that has now been made easier by the worldwide attention terry jones has gotten. dan? >> martha raddatz, thank you. let's talk about all of this now with richard clarke, who was the counterterrorism czar in both the clinton and bush administrations. and he was in that position on 9/11. he's now an abc news consultant. he joins us from virginia. richard, good morning to you. >> good morning, dan. >> so, even though this koran burning has been called off, do you think the damage has been done? has it made us less safe, do you think?

>> it's made us a lot less safe. whenever we do things that support bin laden's theory, that america is at war with islam, that strengthens his recruitment process. so, he's probably recruited thousands of more adherents over the last few weeks, while we argued about a mosque in new york and koran burning. >> there was all this talk when president obama was inaugurated. here's a man whose middle name is hussein. he's spent part of his childhood in a muslim country. he's made a lot of effort to reach out to the muslim world. and in fact, gave an impassioned set of statements on this very issue yesterday. has none of that helped? >> it did help. when he said in his inaugural address, america is not at war with islam, that helped a lot. but the recent controversies have undone all that. and the average muslim in indonesia, or india, or pakistan, could be forgiven for thinking that the united states really is at war with islam.

and that's the fuel that bin laden needs to get support, financial support, suicide bombers, to get people who will join the al qaeda cause. >> martha raddatz brought this up in her piece. why have we not found osama bin laden nine years after the fact? >> well, you know, the world has billions of people on it. and finding one person has always proved difficult when they don't want to be found. but as general petraeus said in your piece, he is out there. he is influential. he is still issuing orders. and he's still issuing orders to attack the united states. >> you were in the white house, as we said, nine years ago, on 9/11. as you look out at the world right now and you survey our anti-terror defenses in this country, what keeps you up at night? what is our biggest vulnerability? >> well, it's still possible for a handful of people, even if al qaeda is reduced to 150 or 200 people. it's still possible for 10 or 12 to come to the united states. they could even be people with

american passports who went overseas and got trained and came back. to get into the united states and cause an attack. it's always going to be possible, no matter what we do. so, we have to anticipate that there will be another attack. and we have to think about what our reaction's going to be when that occurs. last time, a lot of our reaction was counterproductive. and this time, i hope if it happens, we are more realistic. we all want it not to happen. but stopping every terrorist attack is almost impossible. >> have our defenses improved measurably, do you think? >> well, they have, in some areas. certainly, aviation security is much better. but the sort of attack that occurred on the london subway a few years ago on 7/7, that sort of attack could take place on any one of the american subway systems today. there's some targets that are just really, really tough to protect, no matter what you do. >> richard clarke, thank you very much.

we appreciate your input on this anniversary. >> thank you, dan. >> bianna, to you. >> all right, dan. the national transportation safety board is now in charge of the investigation into that deadly gas blast that instantly turned a california neighborhood into a blazing inferno. at least four people were killed in that devastating explosion and dozens more injured and hospitalized. neal karlinsky has the latest. >> reporter: late friday, the first up-close look at the devastation. a foundation where a home once stood. charred shells of cars. chimneys, standing without a house. it was a natural gas pipeline just three feet underground that burst thursday night, sending a torrent of flames through this otherwise peaceful neighborhood. and leveling dozens of homes. officials from the ntsb are investigating but still don't know what caused the pipe to explode. >> the fact that this pipe, this large piece of pipeline was blown the distance that it was

out of the hole in the ground. so, that tells me the magnitude of the explosion that took place. >> reporter: some san bruno residents smelled fumes days earlier. but said, utility did nothing about it. >> about a week ago, it smelled like gas. >> we want to know the answers to those allegations, as well. we will be cooperating with the ntsb, as they investigate that aspect of the accident. so, we want to know what happened. and they will get to the root cause of it. >> reporter: so many survivors of the san bruno fire suffered the same near-death escape. but none of their stories are alike. gayle masunu was burned on the side of her body that was reaching out to save her elderly mother. >> it was a boom, boom, boom. and i couldn't figure out what it was. and the whole house was shaking. it felt like an earthquake, too. >> reporter: meanwhile, some residents are still trying to determine if they have a home to return to. community shelters are filled. what do you think of your home?

do you think you made it? >> i don't know. >> i hope so. everybody says it worked its way around it. but i don't know. >> obviously, nobody thinks this is just a day story. maybe for the media, it's a day or two. but for these people, this is a long haul to kind of begin to rebuild their lives. >> reporter: a long haul that is just beginning. for "good morning america," neal karlinsky, abc news, san bruno, california. >> our thanks to neal. and we're going to have more on this story in our next half hour. just what kind of pipelines are running beneath your neighborhood? and how can you spot dangers? we'll get into all of that. now, we want to turn into that home coming that wasn't. iran was supposed to send american hiker sarah shourd free this morning. she and two of her friends have been imprisoned there for more than a year. but in a last-minute change of plans, they delayed her release. jim sciutto has reportsed many times from iran. he joins us now from washington. jim, this appeared to be a done

deal until late yesterday afternoon. who we know what changed? >> reporter: enormous disappointment for the families. they had been waiting for this for 14 months. and were told it was going to happen today. it appears to be the subject of internal political battles in iran. president mahmoud ahmadinejad has turned it into a personal case. but a political faction wanted to deny him the p.r. victory. the prosecutor in tehran, says there's legal steps that have to be taken. so, more pain for the families. >> so, where does this case go next? >> reporter: well, it's difficult to say because it's clearly become politicized. most people still believe that she will still be released. particularly because she has health problems. discovery of a lump in her breast. the possibility of cancer. but the trouble is, it's unpredictable because there's another political faction in iran that clearly has not been satisfied. you have to wait for that political game to be played out until she can be released.

>> jim, thank you for the latest headline there. it must be so troubling for sarah's family. so close to see her once again. >> right. >> and knowing she's ill on top of that. >> frustrating to have this caught up in internal politics. >> devastating for that family. we want to go the other headlines of the morning. ron claiborne is here with that. >> good morning, everyone. the federal aviation administration is proposing new rules to address the dichblgs pilot fatigue. as lisa stark reports, the changes would double the amount of rest a pilot must have between flights. >> reporter: the crash near buffalo last year took 50 lives and revealed serious safety issues, including tired pilots. in this case, a crew that commuted long distances to work. and did not get enough rest before climbing into the cockpit. the new rules, for the first time, call on airlines to consider a pilot's commute in drawing up schedules. and they dramatically alter how many hours pilots can work. >> we think this took too long. but it certainly didn't take as

long as other administrations took, which didn't do a dang thing. >> reporter: currently, pilots must have eight hours off a day, for rest. but that includes time to get to a hotel, eat a meal and return. meaning they might get four hours of sleep or less. under the new rule, pilots must be scheduled for nine hours of actual rest time. currently, pilots can be scheduled to work a 16-hour day, regardless of whether that means working in the middle of the night. under the new rules, their day will top out at 13 hours. and even less if they're working the late shift. >> the schedules are going to be more resilient. the pilots will be better rested. it's a good thing to do. >> reporter: this has been a long time coming. >> a lot of people have tried. we have succeeded. it's a big day for us. >> reporter: isn't it a shame, though, against the government that it took 20 years to do this? >> it certainly took way too long in coming. i'll acknowledge that. >> reporter: the families of those who died last year applauded today's announcement.

and said the traveling public deserves no less. for "good morning america," lisa stark, abc news, washington. in mexico, 25 people were killed in a series of drug gang attacks in juarez, across the border from el paso, texas. it was the deadliest day in more than two years for the mexican border city. more than 4,000 people have been killed in juarez in the last 2 years. and a new record, world record, for the biggest chocolate bar in the world. a company in armenia made the massive chocolate war. it beat the previous world record set in italy three years ago, by more than a ton. and venus williams is out of the u.s. open tennis tournament. she was defended by defending women's champ, kim clijsters. clijsters plays tonight against vera zvonareva. zvonareva. is that right, bianna? i hope. the men's finals will be played this afternoon. two of them this afternoon. finally, have you ever been kissed by a pony? well, some of the residents of

new jersey nursing homes got kisses from samson, the shetland pony who makes rounds to make people feel better. and the folks at the nursing homes said that being slimed by samson did, indeed, make them feel better. i'm not sure i would do that. >> i'm reading from your voice, i don't know if you want a kiss from that pony. >> i disagree. >> unsanitary, perhaps? >> i think you and samson would get along. >> let's bring samson here next week. and we can test-drive him. mary, don't you think? don't you think mary would be an added plus here. >> the kissing pony. we have kissing stage managers that think they're ponies sometimes. good morning, everyone. we take a look at the northeast. it's absolutely gorgeous today. there's a slight chill in the air. really sunny skies. up and down the mid-atlantic and northeast, temperatures in the 70s. we are checking in on the tropics. tropical storm igor.

>> thank you, mary. we have an mazing story to tell you about this morning. for the first time, a medal of honor will be awarded to a living soldier. president obama called staff sergeant salvatore giunta to tell him he's getting the award and thanked him for his service. >> sergeant giunta is being honored for stopping taliban soldiers from killing fellow soldier when his unit was ambushed the 2007. he was humbled by the news. telling "stars and stripes," i wasn't the only one there that night. they were all doing their jobs. he was 22 years old. >> 22 years old. originally from iowa. he's now serving in italy. it's unclear when he will get that award. >> he ran directly into the ambush and saved three fellow officers. >> after having been shot. and his flak jacket stopped the bullet. >> a date is yet to be announced when he will be honored. we commend his service. coming up, hidden danger. could a massive underground pipeline explosion like the one

in california happen where you live? we'll tell you what you need to know. when i was seventeen i was not good to my skin. long summer days, and not enough sleep. what i wouldn't do for a do-over.

♪ and you're looking at ground zero in lower manhattan today. it's been nine years since the devastating terror attacks there. at the pentagon and in pennsylvania. this is the most tumultuous anniversary yet. we talk to some of the 9/11 families about how they are coping with all of the controversy and how they are moving on. we'll have their stories coming up. good morning, america. i'm bianna golodryga. >> i'm dan harris. this is, of course, saturday, september 11th. also coming up this morning, we're going to lighten things up with a peek into your world. a segment that we call "your week in three words." that will be coming up later. we begin with the massive natural gas explosion that killed at least four people and turned a san francisco neighborhood into what one resident calls something out of dante. federal officials have now taken

over the investigation. this explosion was extraordinary. but it turns out, that incidents involving natural gas pipelines are not. david kerley is in washington with more. good morning, david. >> reporter: good morning, bianna. under this street, just about every street in america, there is a gas line. and there's an incident, a leak or an explosion like the one in san bruno, california, on one of those pipes every other day. the explosions were massive. fire pouring from the gas line. dozens of homes up in flames. 50 people injured. >> that's when i saw the big blast. the big kaboom. i kept saying oh, my god. oh, my god. oh, my god. and that's when he came out to see what oh, my god was all about. >> reporter: this san bruno, california, neighborhood is somewhat rare. running through it, a massive, 30-inch, 50-year-old transmission pipeline, 3 feet under the ground, carrying gas under high pressure. only about 7% of those big lines, which carry gas to utilities for distribution back

at homes, run anywhere close to a neighborhood. >> if you look at a per mile, it's pretty rare. if you happen to be in a community where it's happened, they happen way too often. >> reporter: 329,000 miles of the big pipes. more than 2 million miles of much smaller pipes that carry gas to your house. we're walking down the middle of the street. >> yes. >> reporter: what's underneath here? >> many pipes, the infrastructure of our city, including some type of gas distribution line. >> reporter: this is that san bruno looked like. a pipeline carrying gas to the utility. and the smaller distribution pipes coming back to homes. but most american streets have the smaller two-inch to four-inch pipes running under the street. and get even smaller as they run to your home. but they can still cause explosions. >> it will be at a lower pressure. nonetheless, if it were to break, it would make a significant fire and cause great danger. >> reporter: that's why, for

firefighters, a gas detector is a mandatory piece of equipment. so, is it every day you pull this thing out? >> yes. pretty much. at least once or twice a day. >> reporter: a huge transmission line, bursting and exploding in a populated area like san bruno is rare. one of the last big accidents like it was in texas in the 1940s. and usually, these leaks or explosions are caused by somebody digging or excavating, somebody digging or excavating, somebody digging or excavating, somebody digging or excavating, another utility, next to one of these gas lines. are you worried about your gas lines? here's some tips from the d.c. chief in you're concerned. the rotten egg smell is gas. if you smell it, pay attention. if you hear a large amount of energy escaping, a whoosh, that could be gas. his best advice, get out of the house if you have any worries. and he says, don't be afraid to call 911. firefighters will show up. if they find gas, they'll air out the house and get the utility out there. dan and bianna? >> thank you.

you're looking at live pictures from ground zero, nine years after the attacks. this year, the anniversary is a particularly raw one, given the animosity that's been stirred up by the plans to build an islamic center near the site. and that pastor down in florida, who has been threatening to burn the koran. plans that were ultimately called off. ron has been talking to some of the 9/11, families about how they're dealing with this. >> good morning, again, dan. those controversies for the families of the 9/11 attacks have made this anniversary all that more difficult. but others we spoke with says that what they will be thinking about will be about the loved ones they lost nine years ago today. three months after 9/11, a tiny 2-year-old girl named patricia smith wore the medal of heroism for her mother, a police officer who died at ground zero. today, tricia is 11 years old.

a sixth grader with an angelic smile and a love of horses. she knows her mother only from the memory of others. family photos. her mom helping others to safety. and in her own imagination. when you see those pictures, tricia, what goes through your mind? >> they remind me of how great she was. >> reporter: she still wears a necklace with her mom's picture, just like she did in 2002. >> what is that? >> a necklace. >> it's a necklace. and whose picture is that? >> my mom. >> reporter: nine years ago, patricia's father, james smith, was also a new york city police officer. >> i've been thinking about what laura would be doing today if she was here with us. >> reporter: every 9/11 since then, he and patricia attend the memorial service at the site of the world trade center towers. >> i don't see it as a heavy day because i don't dwell on her death. i try to celebrate what her life was about. all of the people that are here today because of her actions.
